Among other things, the present disclosure provides technologies for oligonucleotide preparation, particularly chirally controlled oligonucleotide preparation, which technologies provide greatly improved crude purity and yield, and significantly reduce manufacturing costs.
Stereodefined oligonucleoside H‐phosphonates were synthesized on a solid support using diastereopure nucleoside 3′‐O‐oxazaphospholidine monomers. Several stereodefined backbone‐modified analogues were obtained with the oligonucleoside H‐phosphonates as precursors (see scheme; BPRO=protected nucleobase, DMTr=4,4′‐dimethoxytrityl, Th=thymin‐1‐yl, TfO−=triflate).
